Application: With alkynes forms 2-alkenyldibromoboranes, which show reversed regiochemistry in Diels-Alder reactions as compared to BBN. Intermediates generated from 1-alkynes couple to alkyl halides providing trisubstituted alkenes. Reacts with chiral sulfonamides to provide precursors of chiral glycidol esters, acetate diols, β-hydroxy esters, and amino acid esters. Useful for the synthesis of precursors to group 13-15 semiconductor materials.
Application: Reactant for preparation of:. Drug intermediate 6-nitro-L-DOPA. Luminescent polystyrene derivatives with sterically protected carbazolylborane moieties. High-quality boron-doped graphene via Wurtz-type reductive coupling reaction. Mercapto-(+)-methamphetamine haptens for synthesis of (+)-methamphetamine conjugate vaccines with improved epitope densities. Micrometer-sized organic molecule-DNA hybrid structures. Borane complexes via electrophilic aromatic borylation reactions. A 5-HT2C receptor agonist. Biphenyl-derivatives possessing tertiary amino groups as β-secretase(BACE1) inhibitors for the treatment of Alzheimer′s disease. A highly near-IR region fluorescent p-extended boron aza-dipyrromethene moiety unit. Tetrahydroisoquinoline derivatives via intramolecular cyclization of methoxy-substituted N-phenethylimides
